-LRB- CNN -RRB- -- A typhoon that left at least 18 people dead and thousands displaced in the Philippines was expected to move offshore Wednesday afternoon , the state-run Philippines News Agency reported early Wednesday .

A baby boy was among the dead after Typhoon Nesat -- referred to in the Philippines as Pedring -- slammed into the Philippines Tuesday , Philippine authorities said .

Four people were reported killed in Metro Manila , two in Central Luzon , and one in Catanduanes , the Office of Civil Defense said . Three more were reported injured and four were missing as of Tuesday afternoon .

Pedring , struck the agricultural provinces of Isabela and Aurora the hardest . But storm alerts were also issued for more than 40 other areas , including Metro Manila , the state weather bureau Philippine Atmospheric Geophysical and Astronomical Services Administration -LRB- PAGASA -RRB- said .

More than 64,000 people have been affected by the typhoon , the National Disaster Risk Reduction and Management Council -LRB- NDRRMC -RRB- said , with several thousand families now being helped in evacuation centers .

More than 100 people have been rescued across the country , the NDRRMC said , many of them from boats .

In Albay , in southern Luzon , more than 3,000 people were affected , the state-run news agency said early Wednesday .

The storm was centered about 300 kilometers -LRB- 186 miles -RRB- northwest of Baguio City , in northwestern Luzon , the state-run news agency said , citing PAGASA .

As of 6 a.m. Wednesday , PAGASA said , Pedring had maximum sustained winds of 120 kph -LRB- 75 mph -RRB- near the center , with gusts of up to 150 kph -LRB- 93 mph -RRB- and was forecast to move west-northwest at 19 kph .

The presidential palace announced the suspension of all classes for schools and work for government agencies in Manila and other affected areas . The Philippine Stock Exchange also suspended trading .

Some roads around Manila were impassable due to flooding and falling debris , including branches that had been ripped off trees .

Several areas in Metro Manila and nearby provinces were without electricity as the powerful storm cut power and transmission lines .

DJ Santa Ana , head of news operations at TV5 in Manila , told CNN it was likely to take some time to restore the power supply in major parts of Metro Manila .

Santa Ana said people in the capital remained calm as the rain kept coming down , although one part of eastern Manila had to be evacuated because of flooding .

Between a half-inch to 1 inch of rain an hour is forecast within the 650 km diameter of the typhoon , state forecasters said .

CNN iReporter Sherbien Dacalanio said power was out in some parts of Quezon City for hours . Several restaurants had to close down because of the high winds and many people did not venture out .

Dacalanio said the winds had uprooted street lights and brought down trees and road signs , but that luckily there was no flooding near his home .

At least 46 domestic flights were canceled and six international flights were delayed due to the storm , aviation officials said .
